Effect of alcohol dehydrogenase 1C (ADH1C) genotype on vitamin A restriction and marbling in Korean native steers

Abstract

The interaction between vitamin A restriction and TC type of <i>ADH1C</i> gene could have the potential of increasing the marbling in Korean native steers. These results indicated that steers with TC type of the <i>ADH1C</i> gene were more sensitive to the change of serum vitamin A than TT types. Furthermore, this finding has the potential to enable a higher marbling score under the condition of vitamin A restriction in Korean native steers.
